In Baltimore, an extremely high number of crimes were committed by juveniles. To address this problem, the U.S. Department of Housing and Urban Development commissioned a study. Duncan, Hirschfield, and Ludwig (2000) were responsible for the study. They welcomed 336 teens ages 11 to 16 and their families and helped them move from a high-poverty neighborhood to a low-poverty neighborhood. They followed regularly throughout the duration of the program which lasted three and a half years. They found that once they were moved away from poor neighborhoods, overall crime committed by these juveniles decreased. The results suggest that property crimes among study participants were higher in poorer neighborhoods due to better target matching in that neighborhood. The study also found that the reduction in robberies was the most significant change among the individuals studied. This is phenomenal since the social cost of theft is much higher than the perceived risk of additional property.
